dReferr-ing to Fig. 1,"it wi'1-l beobserved that r? the strip illustratedcomprises an'uppersec- "-tli -tl'on 10 and a lower section" '11, saidtwo sec- 'tionsi being substantially of the same thicktively thick top port-ion 15 and a relatively thin rib portion 16 depending therefrom, the

lower section 17 being also relatively thin and welding or brazing process, preferably by g spot welding as shown at 18. *Iii-FigL 3-theupper portion 19 has a section similar to that of upper portion 14 of theist'rip just described, being composed of a relativelythick. upper portion 20 and a relatively thin portion 21 depending therefrom.

. The lower section 22 however, instead of being placed-edge to-ed-gevwith' rib portion 21,

has its upper edge portion overlappingsaid brazed to said --r-ib,'this arrangement provid-ing astrong -a-nd more positive con-nee t t-ion.

In this strip the lower section is-shown pro- :vided with a different type of anchoring -means which are inthe-form of open top cup .2, because the longitudinal continuity of the 1 ,inetal section isnot. destroyed, said section being strengthened; rather. than weakened. by

the cup members.

A similar, procedure may be followed in joining the two sections of the strip shown in Fig. 8, where 39 is the upper section and 40 is the lower section, the inner edge portion-of said'lower section being offset laterally of thebodyfi thereofas shown at 41, forming a recess within which may be placed the lower edge portion of the upper section; the upper edge of v the lower section being bent laterally of the body of said section to form a flange 42, which may act as anchoring and positioning means for the strip while at the same time increases its strength and rigidity.
